Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71544, here are decompositions:
- 7 + 71537 = 71544
- 17 + 71527 = 71544
- 41 + 71503 = 71544
- 61 + 71483 = 71544
- 71 + 71473 = 71544
- 73 + 71471 = 71544
- 101 + 71443 = 71544
- 107 + 71437 = 71544
Showing the first eight; more decompositions exist.
